If such a swelling occurs, it is important not to squeeze it, as the nose is the so-called “Danger Triangle” and squeezing it may cause an intracranial infection. The correct treatment is to apply warm compresses to promote the swelling to subside as soon as possible. If the swelling is broken, you need to go to the hospital for further treatment. Another type of swelling that can be seen on the nose is hemangioma. The more obvious characteristics are: usually present at birth, presenting red, dark red prominent swelling, and the normal skin boundary is clear, sometimes you can see the size of the swelling in the lying down when shrinking, standing position increased, more obvious when upside down. As the classification of hemangioma is complicated, different kinds have different treatment methods. Therefore this condition usually needs to be examined and treated in a specialized hospital. In fact, the skin swelling in the nose that most people worry about the most is a malignant tumor. Possible growth of malignant tumors in the nose can generally be manifested as larger swellings with a rough or cauliflower-like surface, which will have superficial debris shedding, irregular borders, and sometimes break and bleed. If you find such a swelling, you need to go to the hospital as soon as possible, remove the swelling as soon as possible and make a pathology section examination to clarify the nature of the swelling, and then make progress in treatment or observation according to the situation. The nose is located in the center of the face, so if there is a mole, it will be particularly conspicuous, affecting the beauty and self-confidence of the individual. The presence of moles not only affects aesthetics, but also some moles may undergo malignant changes. Therefore, it is very important to get rid of moles on the nose. So, how to get rid of moles? Mole removal methods can be categorized into laser and surgical excision. So, under what circumstances, the mole on the nose can not be treated with laser and must be removed? Surgical excision is required if the mole is considered to be potentially malignant. Signs that a mole may undergo malignant changes: pigmented moles that suddenly increase in size, turn black, become inflamed, break out, crust, and bleed easily; pigmented moles that are often rubbed by washing the face or in daily life, and some larger pigmented moles that particularly affect the appearance; pigmented moles that have been treated with laser before but have residual pigmented moles later on.
